Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625422, here are decompositions:

11 + 31625411 = 31625422
29 + 31625393 = 31625422
41 + 31625381 = 31625422
71 + 31625351 = 31625422
383 + 31625039 = 31625422
443 + 31624979 = 31625422
593 + 31624829 = 31625422
641 + 31624781 = 31625422

Showing the first eight; more decompositions exist.
